George Washington drafted this survey of Captain John Posey's property on October 10, 1769. Posey was George Washington's neighbor, and lived just a mile downriver, southwest, of Mount Vernon where he operated a public ferry across the Potomac to Maryland. This survey is particularly significant to Mount Vernon because Washington later expanded his estate by purchasing land from Posey. Washington describes, "At the particular request of Capt. Posey, I surveyed a slipe of Land which he bought of Mr. Marshal, and which is now in dispute… Represented in the above plat between the docked lines AB&C and the River."

For other documents concerning this tract of land see MS-5650 and MS-5874.
